Trailer Breakaway Switch Wiring Diagram

By | June 8, 2022



Trailer breakaway switches are a critical component of any trailer’s safety system. By preventing the trailer from becoming un-hitched in the event of an accident or sudden stop, these switches can help keep you and your cargo safe and sound.

When it comes to wiring up your breakaway switch, it’s important to make sure you're doing it correctly. Without the proper wiring setup, your switch won’t be able to protect you. It’s essential that all components are properly connected and placed in the correct locations.

The first step when wiring a breakaway switch is to consult the trailer breakaway switch wiring diagram for your specific model. This will give you the best idea of which parts are necessary, as well as where they should go. The most common components are the battery, the switch itself, and the brake wire. The battery should be installed within 18 inches of the trailer A-frame, while the switch should be mounted toward the front of the trailer. The brake wire should be connected between the switch and the tow vehicle.

Once you’ve familiarized yourself with the diagram and gathered your components, it’s time to start wiring. Start by connecting the battery, making sure that it’s securely fastened. Then connect the switch by running the lead from the breakaway switch to the ground terminal. From there, connect the brake wire, which runs from the breakaway switch to the tow vehicle. Make sure everything is tightly secured and double-check your work to make sure you’ve followed the diagram correctly.

Once the wiring is complete, it’s a good idea to test the switch to make sure it’s working properly. Before you hit the road, give the switch a few pulls to make sure it’s activating the brakes. It’s also important to regularly check your wiring and components to make sure everything is still securely attached.

By taking the time to properly install and test your trailer breakaway switch, you can ensure that your trailer is safe and sound on the road. With the right wiring diagram in hand, you’ll be able to quickly and effectively set up your switch - giving you the peace of mind of knowing you and your cargo will be protected.
